She was consulted particularly over the...

Noether's theorem
http://en.wikipedia.org/wiki/Noether%27s_Theorem Noether’s (first) theorem states that any differentiable symmetry of the action of a physical system has a corresponding conservation law. The theorem was proved by German mathematician Emmy Noether in 1915 and published in 1918.[1] The action of a physical system is the integral over time of a Lagrangian function (which may or may not be an...

Overcoming ‘Physics Envy’
http://www.nytimes.com/2012/04/01/opinion/sunday/the-social-sciences-physics-envy.html?ref=opinion&pagewanted=print Economists, political scientists and sociologists have long suffered from an academic inferiority complex: physics envy. They often feel that their disciplines should be on a par with the “real” sciences and self-consciously model their work on them, using language (“theory,”...
